====== Connect to multiple VPNs on Windows ======
On Windows OpenVPN by default installs one TAP network interface. If you want to connect to multiple VPNs simultaneously you need an interface for each VPN.

You can add a additional adapter by a batch file provided by the TAP driver. Open a command prompt with administrative rights and change to the TAP install folder.


  c:\> cd "C:\Program Files\TAP-Windows\bin"

and call

  addtap.bat

Example:
<code>
C:\Program Files\TAP-Windows\bin>addtap.bat

C:\Program Files\TAP-Windows\bin>rem Add a new TAP virtual ethernet adapter

C:\Program Files\TAP-Windows\bin>"C:\Program Files\TAP-Windows\bin\tapinstall.exe" install "C:\Program Files\TAP-Windows\driver\OemVista.inf" tap0901
Device node created. Install is complete when drivers are installed...
Updating drivers for tap0901 from C:\Program Files\TAP-Windows\driver\OemVista.inf.
Drivers installed successfully.

C:\Program Files\TAP-Windows\bin>pause
Press any key to continue . . .
</code>

and check it:

<code>
cd "Program Files\OpenVPN\bin"

C:\Program Files\OpenVPN\bin> openvpn.exe --show-adapters
Available TAP-WIN32 adapters [name, GUID]:
'Local Area Connection 2' {DD2A53C5-63BD-492A-A7F4-94E724007B2A}
'Local Area Connection 3' {EF7623C03-542A-34E8-B633-E3B742983E3}
</code>

You can also rename the interfaces now through the GUI (Control Panel\Network and Internet\Network Connections).


Put your .ovpn config  and certificates files to the //C:\Program Files\OpenVPN\config// folder and add the ''nobind'' to each config so that a dynamic (UDP) source port is used for each VPN session respective openvpn process.

When a static assignment between a VPN and specific interface is necessary add the TAP Interfacename as parameter of the ''dev-node'' option to the openvpn config file:

  dev tap
  dev-node "Local Area Connection 3"
